not english, but i'll help nonetheless. not sure what youre asking though
1:
5x+2=-(3x-22)
distribute the negative
5x+2=-3x+22
isolate x
5x+3x=+22+2
8x=24
divide by 8
x= 3
2:
flip it vertically
5x+2
- 3x-22
2x+24=180
isolate x
2x=180-24
2x=156
divide both by 2
x=78
3:
5x+2=3x-22
isolate the x
5x+3x=-22+2
8x=-20
divide both by 8
x=-2.5
4.
combine like terms
5x+3x+2-22=180
8x-20=180
isolate the x
8x=200
divide by 8
x=25
